Per Stereophile,

The Bryston 7B-ST monoblock power amplifier is an exceptional product. It's very powerful, and joins my reference Krell KSA-250 as an amplifier that can handle any loudspeaker load, play wide dynamic range music effortlessly, and excel in imaging and soundstaging. It can "wake up" reticent dynamic loudspeakers over their entire sonic range; in particular, it brought dry, reticent top ends to life. It equaled the Class A recommended amplifiers at my disposal—the Mark Levinson No.331 and the discontinued Krell KSA-250—in dynamics, transparency, and ability to transmit music's rhythmic pace.

This solid-state monoblock should be auditioned by anyone who needs a new amplifier for driving high-impedance electrostatic loudspeakers, or dynamic loudspeakers that seem somewhat bass-shy. The Bryston 7B-ST rates a solid Class A recommendation. –Larry Greenhill, Stereophile
